Quick Answer
For the Castañer VAIAN heeled sandal, choose your usual size—the fit runs true to size. Focus on the ankle strap and heel grip for all-day comfort.
Why True-to-Size Fit Matters
The VAIAN heeled sandal is designed to fit true to your usual size, which simplifies ordering. However, heeled sandals can feel different from closed shoes because your foot can slide forward. Understanding how the straps and heel work together will help you avoid discomfort.
Comfort Considerations for Heeled Sandals
Heeled sandals put more pressure on the ball of your foot. The VAIAN's leather and suede upper will soften with wear, but the initial break-in period requires patience. If you're between sizes, consider how you'll wear them—for extended standing or walking, a snugger fit might be better to prevent rubbing.
How to Ensure the Perfect Fit and Comfort
- Measure your foot length: Place your heel against a wall and measure from the wall to the tip of your longest toe. Compare this measurement to Castañer's size chart to confirm your usual size. Do this in the afternoon—feet swell during the day, so you'll get a more accurate size.
- Try them on with the right socks: If you plan to wear the sandals barefoot, try them on barefoot. If you'll wear them with hosiery, wear the same type of socks or tights during your fitting. Avoid thick socks if you'll wear them barefoot—they can make the fit feel looser than it is.
- Check the ankle strap fit: The ankle strap should be snug but not tight—you should be able to slide one finger between the strap and your ankle. If the strap is too loose, your foot may slide forward. If the strap is too tight, consider a half-size up or a different style with an adjustable strap.
- Walk and test the heel grip: Walk around on a carpeted surface to see if your heel lifts out of the shoe. A slight lift is normal, but if your heel slips significantly, the sandal may be too big. If your heel slips, try a half-size down or use a heel grip insert for a better fit.
- Break them in gradually: Wear the VAIAN sandals for short periods at home to let the leather and suede soften and mold to your feet. Increase wear time gradually to avoid blisters. Apply a leather conditioner to soften the straps, but test it on a small area first.
